However, the above-mentioned conventional telephone body 50 is configured such that the circuit board 55 screwed to the upper case 58 is received by the plurality of bosses 57 on the lower case 56 side. When a board is to be incorporated in addition to the circuit board 55, for example, if one board is arranged on the lower side of the circuit board 55 in FIG.
It is necessary to provide a through hole for a boss in a portion corresponding to the above.
Therefore, there is a problem that the size of the substrate is increased by the amount of the through hole.

[0005] An object of the present invention is to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a telephone which can save the space of the telephone main body.

[0006]

In order to achieve the above object, a telephone according to the present invention is a telephone having at least an external push-button operation section and a telephone body having a circuit board and an operation board inside. The telephone body includes a substantially planar concave portion for holding the operation board, and receives a pressing force transmitted from the push button operation section onto the operation substrate at the recess.

In the above telephone, the recess is
A plurality of projections for holding the operation board are provided on the plane.

According to the telephone having the above structure, the telephone body is provided with the concave portion, and the operation board is held by the concave portion and receives the pressing force transmitted to the operation substrate. Can be fixed to the back side of the. In addition, the operation board and the push button operation section can be integrated and temporarily held in the recess at the time of assembly, and the number of fixing screws from the back side can be reduced to a minimum.

Further, by disposing a plurality of projections for holding the operation board on the plane of the concave portion, the operation board can be supported at a plurality of points, and the delicate warping of the operation board can be reduced. By adjusting the length, it can be absorbed.

A pair of insertion holes (not shown) for inserting a pair of locking claws 33 of the stand 30 are formed in the bottom surface 16. The stand 30 can be held by the stand fitting portion 15 by fitting the bottom portion 31 of the stand 30 into the stand fitting portion 15 and inserting a pair of locking claws 33 into the insertion hole. .

Further, on the bottom plate of the telephone body 10,
A connection hole (not shown) for connecting the connection terminal 6a of the handset cord 6 is formed. A connection hole (not shown) for connecting the connection terminal 29a of the modular cord 29 is formed near the rear end of the bottom plate of the telephone body 10.

The stand 30 is provided with a front case 30.
a and the rear case 30b are combined, and the bottom part 31 formed in a substantially rectangular shape is formed one size smaller than the stand fitting part 15. Further, a receiving section 35 for receiving the transmitting section 2a of the handset 2 is formed in a lower part of the front surface of the stand 30 in a state of being depressed in a vertical cross section.
An earpiece 2b of the handset 2 on the front upper part of the stand 30
A corner 36 on which the jaw 2e is mounted is formed. A hook claw 38 that supports the handset 2 at a predetermined position is formed in the corner portion 36 by fitting an insertion hole (not shown) of the handset 2.

The handset 2 has a rear cover 3 formed in a substantially rectangular shape, a transmission section 2a formed at a lower end 4, and a reception section 2b formed at an upper end 5. Connection holes 7a, 7b for detachably connecting the connection terminals 6b of the handset cord 6 are formed in the left and right side surfaces 2c, 2d of the transmitting section 2a, respectively. Therefore,
The handset cord 6 can be appropriately pulled out from both sides of the handset 2 according to the use state.
